ELAD FDM-77 SDR HF/VHF Receiver

All mode LW, MW, HF Software Defined Radio Receiver
The FDM77 is conceived as a SDR (Software Defined Radio). This approach means that the receiving set is composed of a Hardware RF front-end and a PC with ELAD Software Radio. The Software Radio is the operator main interface (GUI) for the control of the radio (Input RF, Tuning, Setup, Mode, Display, Scan and AF) and is also used to decode and reproduce the audio through the PC soundcard.

Price when new in 2013: EUR 640
